Disclosed is a heat exchanger (1) composed of a stack of foils or plates (F), particularly a micro heat exchanger. Breakthroughs (4, 5, 7, 8) and ducts (2, 3) that extend on the level of the plate are configured in the individual plates (F). The plates (F) are placed on top of each other in such a way that the ducts (2, 3) intersect in successive plates (F), a first fluid (P) flows through the ducts (2) of one plate (F) while a second fluid (W) flows through the ducts (3) of the adjacent plate (F), feeding tubes and discharge tubes are embodied on the external faces of the resulting blocks of intersecting ducts (2, 3) by means of the breakthroughs (4, 5, 7, 8), and at least one of the two fluids (P, W) flows through the ducts of the respective plate antiparallel to one another or alternately in opposite directions. |
